[0001] The invention relates to the technical field of packaging machinery, and in particular to a material cutting and packaging machine. Background Art

[0002] The bag cutting machine is often used in food packaging, also known as the bag throwing machine. It cuts the bag strip into independent small bags and puts them on the conveyor belt of the production line or in the food packaging. The bag in the food packaging can be powder bag, sauce bag, vegetable bag or deoxidizer bag, etc.

[0003] In the prior art cutting and packing machines, the material bag belt is fed into the cutting part by an intermittent feeding wheel, and then cut one by one by the cutting knife for feeding, such as the patent roll packaging bag discharge device with publication number CN101407255B and the patent roll desiccant packing machine with publication number CN208217162U.

[0004] The prior art material bag cutting machine has at least the following deficiencies: before cutting, since the rolled or reciprocatingly stacked material bag belt needs to be neatly conveyed to the cutting position, the material bag belt needs to be turned for multiple times during conveying, and the turning angle is too large. Vacuum material bags and material bags with poor flexibility are not easy to turn and pass through at a large angle. Vegetable material bags are easily crushed after multiple large-angle turns. Intermittent conveying and cutting one by one, and cutting during the interval time of intermittent conveying, have a long feeding time interval, which limits the improvement of cutting and feeding efficiency.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0033] Specific embodiments of the cutting and packing machine provided by the present invention: See also Figure 1-14 The cutting and packaging machine comprises a cylinder 1, a rotating component 2, a clamping component 3, a cutting component 4, a blanking cover 5 and a blanking component 6.

[0034] The cylinder 1 has an inverted cone 101 at its lower end. The inverted cone 101 has an opening at its lower end for feeding a material bag. The opening corresponds to the conveyor belt or directly corresponds to the food package on the conveyor belt.

[0035] The clamping assembly 3 rotates around the outside of the cylinder 1 and clamps the material bag belt 8 to move so that the material bag belt 8 is wrapped around the outside of the cylinder 1.

[0036] The rotating assembly 2 drives the clamping assembly 3 to rotate outside the cylinder 1. The rotating assembly 2 includes a rotating frame 201, the rotating frame 201 is rotatably installed on the upper side of the cylinder 1, and a first motor 202 that drives the rotating frame 201 to rotate. The clamping assembly 3 is installed on the outside of one end of the rotating frame 201 and is located on the outside of the upper end of the cylinder 1.

[0037] An annular slide groove 102 is provided on the upper side of the cylinder wall of the cylinder 1, and sliders 203 that slide along the slide groove 102 are provided on the lower sides of both ends of the rotating frame 201; the rotating frame 201 is a triangular frame body, and a cross-shaped bracket supporting the first motor 202 is provided on the inner side of the upper end of the cylinder 1; so that the rotating frame 201 and the clamping assembly 3 can rotate stably on the upper end of the cylinder 1.

[0038] An annular base 104 for supporting the material bag belt 8 is provided on the outer side of the upper part of the cylinder 1, and a plurality of vertical rod-shaped fixed knives 105 are provided on the upper side of the edge of the base 104. The fixed knives 105 are evenly spaced and distributed within three-quarters of the circumference. A reinforcing rod is provided on the upper side of the fixed knife 105, and the reinforcing rod is a circular arc rod structure of three-quarters of a circle; the base 104, the fixed knife 105 and the outer side of the cylinder 1 form a space for placing the material bag belt 8, and the material bag belt 8 is wrapped around the outer side of the cylinder 1 in the space.

[0039] A plurality of guide roller groups 7 are arranged at the outer extension position of the position where the material bag belt 8 enters the outer side of the cylinder 1. The guide roller group 7 includes two rollers located on both sides of the material bag belt 8 and a bracket for supporting the rotation of the rollers. The guide roller group 7 provides guidance for the material bag belt 8 to enter the outer side of the cylinder 1. The material bag belt 8 is wound around the outer side of the cylinder 1 in the tangential direction on the outer side of the cylinder 1.

[0040] The rotating frame 201 drives the clamping assembly 3 to rotate, and the end of the material bag belt 8 clamped by the clamping assembly 3 passes through the space between the fixed knife 105 and the cylinder 1, so that the material bag belt 8 surrounds three quarters of the cylinder 1; then the rotating frame 201 stops rotating.

[0041] The clamping assembly 3 includes an inverted U-shaped seat 301, an inverted U-shaped swing arm 302 that swings back and forth, and a second motor 303 that drives the swing arm 302. The upper end of the inverted U-shaped seat 301 is connected to the rotating frame 201, and the upper end of the swing arm 302 is rotatably installed on the inner side of the inverted U-shaped seat 301. The second motor 303 is installed on one side of the inverted U-shaped seat 301. The height of the inverted U-shaped seat 301 is higher than the fixed knife 105; the second motor 303 can make the swing arm 302 higher than the fixed knife 105 by swinging the swing arm 302. When the swing arm 302 is in a vertical state, the swing arm 302 extends into the narrow space between the fixed knife 105 and the cylinder 1 and moves in the narrow space, and the height corresponds to the material bag belt 8.

[0042] When the clamping assembly 3 is unloaded, the swing arm 302 rotates to a horizontal state, which will not interfere with the end of the material bag belt 8 that is about to enter the outside of the cylinder 1; when the clamping assembly 3 clamps the material bag belt 8 and moves, the swing arm 302 is in a vertical state. At the position where the material bag belt 8 is about to enter the outside of the cylinder 1, the rotating swing arm 302 is more likely to cooperate with the end of the material bag belt 8. In order to make it easier for the end of the material bag belt 8 to enter the inner side of the U-shaped opening of the swing arm 302, the side surface of the U-shaped opening of the swing arm 302 is chamfered.

[0043] An oil storage chamber 304 is provided in the swing arm 302, and a piston 305 is provided in the oil storage chamber 304. An automatic telescopic rod 306 for driving the piston 305 to move back and forth is installed on the swing arm 302. The automatic telescopic rod 306 is preferably an electric telescopic rod. An oil bag 307 for clamping the material bag 8 is provided on the inner side of the inverted U-shaped opening of the swing arm 302. The oil bag 307 is connected to the oil storage chamber 304 and is filled with oil.

[0044] The telescopic end of the automatic telescopic rod 306 extends, and the piston 305 compresses the oil in the oil storage chamber 304, so that the oil enters the oil bag 307 on the inner side of the swing arm 302. The oil bag 307 is filled with oil and expands to squeeze the end of the material bag belt 8, so as to clamp the material bag belt 8; the telescopic end of the automatic telescopic rod 306 retracts, and the piston 305 draws oil, so that the oil in the oil bag 307 enters the oil storage chamber 304. The volume of the oil bag 307 shrinks, and the material bag belt 8 is released.

[0045] The cutting assembly 4 includes a plurality of cutters 401 that slide through the side wall of the cylinder 1 , and the cutters 401 are evenly arranged within three quarters of the circumference of the side wall of the cylinder 1 ; the cutters 401 synchronously act to cut the material bag belt 8 outside the cylinder 1 ; the fixed knife 105 cooperates with the cutters 401 to shear the material bag belt 8 .

[0046] The cutter 401 is a block structure, and a knife hole 103 corresponding to the cutter 401 is provided on the side wall of the cylinder 1 for the cutter 401 to slide through. The wall of the cylinder 1 between adjacent knife holes 103 is radially corresponding to the fixed knife 105 on the outside thereof. The edge of one side of the block cutter 401 has a cutting edge. After cutting the material bag belt 8 with the fixed knife 105, the block cutter 401 moves outward from the cylinder 1, and can contact the cut material bag with a larger area, push the material bag outward, and finally make the material bag pass through the gap between the adjacent fixed knives 105 and fall outside the cylinder 1.

[0047] The inner side of the cutter 401 is connected to a driving rod 402, and the inner side of the cylinder 1 is provided with a rotating disk 403 and a third motor 404 driving the rotating disk 403 to rotate; the inner side of the cylinder 1 is provided with a cross-shaped bracket supporting the third motor 404 and the rotating disk 403. The rotating disk 403 is provided with a plurality of arc holes 405 corresponding to the driving rods 402 one by one, and the inner ends of the driving rods 402 extend into the corresponding arc holes 405, and the distances from the two ends of the arc holes 405 to the center of the rotating disk 403 are different.

[0048] The arc holes 405 are evenly arranged on the rotating disk 403 , and each arc hole 405 corresponds to a group of cutters 401 and driving rods 402 . When the rotating disk 403 rotates, all driving rods 402 and cutters 401 can be moved simultaneously.

[0049] The third motor 404 drives the turntable 403 to rotate back and forth, so that the two ends of the arc hole 405 cooperate with the driving rod 402 respectively, thereby realizing the synchronous extension of the cutter 401 to cut the material bag belt 8 and the synchronous retraction. After retraction, the outer end of the cutter 401 slightly protrudes from the outside of the cylinder 1 and does not affect the circumferential movement of the material bag belt 8 on the outside of the cylinder 1.

[0050] In this embodiment, the material bag is a three-side sealed material bag. One side of the cutter 401 is provided with a serrated edge, and one side of the fixed knife 105 is provided with saw teeth matching the edge. After cutting, both edges of the material bag have saw teeth, which is convenient for tearing the material bag open when using it.

[0051] The material drop cover 5 surrounds the outer side of the cylinder 1 and has a plurality of falling channels corresponding to the material packages after cutting; the material drop cover 5 includes an outer shell 501 and a plurality of partitions 502, the outer shell 501 is a three-quarter circular cylindrical structure, and the partitions 502 are connected between the inner side of the outer shell 501 and the outer side of the cylinder 1.

[0052] The number of the falling channels is the same as that of the cutters 401 and they correspond one to one. The cut material packages pushed out by the cutters 401 enter the falling channels from the upper ends of the falling channels at the same time and fall on the lower ends of the falling channels.

[0053] The material unloading assembly 6 includes a plurality of unloading gates 601, the number of which is the same as the number of the cutters 401 and corresponds vertically one by one. The unloading gates 601 are installed at the lower part of the side wall of the cylinder 1 and correspond to the lower ends of the falling channels. The lower end of the material unloading cover 5 is inverted conical, so that the material bags in the falling channels move toward the unloading gates 601 on the side wall of the cylinder 1; the unloading gates 601 are opened in sequence so that the material bags after cutting fall from the inner side of the cylinder 1 in sequence and finally fall from the lower end opening of the inverted conical part 101.

[0054] The unloading door 601 is hinged to the side wall of the cylinder 1, and a torsion spring 602 is arranged at the hinge between the unloading door 601 and the cylinder 1 to keep the unloading door 601 normally closed. An L-shaped rocker arm 603 is connected to the upper side of the middle part of the unloading door 601. The rocker arm 603 includes two long rod parts and a short rod part which are vertically integrated, and the short rod part is connected to the unloading door 601. In this way, the unloading door 601 can be opened at a larger angle by swinging the rocker arm 603 at a small angle.

[0055] A door hole 106 corresponding to the unloading door 601 is provided on the side wall of the cylinder 1, and a notch 107 corresponding to the swing rod 603 is provided on the upper middle side of the door hole 106. The swing rod 603 enters the notch 107 when swinging, so that the cylinder 1 does not affect the swing of the swing rod 603 and the rotation of the unloading door 601.

[0056] The material discharging assembly 6 further includes a wheel disc 604 for driving the swing rod 603 to swing and a fourth motor 605 for driving the wheel disc 604 to rotate. The wheel disc 604 is rotatably mounted in the cylinder 1, and a cross-shaped bracket for supporting the wheel disc 604 and the fourth motor 605 is provided on the inner side of the cylinder 1. An annular groove 606 is provided on the outer ring side of the wheel disc 604, and the torsion spring 602 causes one end of the swing rod 603 away from the material discharging door 601 to abut against the inner side of the annular groove 606, and a protrusion 607 is provided in the annular groove 606; the outermost end of the protrusion 607 is located in the annular groove 606.

[0057] When the bottom of the annular groove 606 supports the rocker arm 603, the torsion spring 602 closes the unloading door 601, and the lower end of the unloading door 601 abuts against the inner side of the lower end of the shell 501; when the outermost end of the protrusion 607 supports the rocker arm 603, the rocker arm 603 overcomes the elastic force of the torsion spring 602 and swings to make the unloading door 601 swing toward the inner side of the cylinder 1 to open.

[0058] A spherical head is provided at one end of the rocker arm 603 away from the unloading door 601, which can well interfere with the inner side of the annular groove 606; when the unloading door 601 is in a normally closed state, the rocker arm 603 interferes with the inner lower edge of the annular groove 606, and the height of the annular groove 606 is not less than seven times the outer diameter of the spherical head; because when the rocker arm 603 swings, the rocker arm 603 and the spherical head produce vertical movement, the higher annular groove 606 can adapt to the vertical movement of the end of the rocker arm 603, thereby preventing the rocker arm 603 and the spherical head from detaching from the annular groove 606.

[0059] The fourth motor 605 drives the wheel 604 to rotate, and the protrusion 607 lifts up each swing rod 603 in turn. The swing rod 603 swings to open the unloading door 601, and then the material bag at the bottom of the falling channel corresponding to the unloading door 601 falls through the door hole 106, and the material bag passes through the inverted cone 101 of the cylinder 1, completing the feeding to the packaging conveyor line. The unloading door 601 opens in turn; after the protrusion 607 leaves, the torsion spring 602 closes the unloading door 601.

[0060] The cutting and packing working process of the cutting and packing machine: Step 1: The rotating frame 201 of the rotating assembly 2 rotates to move the clamping assembly 3 to a position where the material bag belt 8 enters the outer side of the cylinder 1; Step 2: The second motor 303 rotates the horizontal swing arm 302, and the inverted U-shaped portion of the swing arm 302 rotates to the outside of the end of the material bag belt 8 and becomes vertical. The telescopic end of the automatic telescopic rod 306 extends out to press the oil, and the oil bag 307 expands to clamp the end of the material bag belt 8 on the inner side of the swing arm 302; Step 3: The rotating frame 201 rotates to drive the clamping assembly 3 to rotate, so that the material bag belt 8 surrounds three quarters of the circumferential side wall of the cylinder 1, forming a three quarter arc of the material bag belt 8 located between the outer side of the cylinder 1 and the fixed knife 105; Step 4: The telescopic end of the automatic telescopic rod 306 is retracted, the oil bag 307 is contracted, the material bag belt 8 is released, and the second motor 303 drives the swing arm 302 to rotate to a horizontal state; Step 5: The third motor 404 drives the rotating disk 403 to rotate a certain angle, so that the other end of the arc hole 405 cooperates with the driving rod 402, thereby extending all the cutters 401, and one side of the cutter 401 cooperates with the fixed knife 105 to simultaneously realize the cutting of all the material bags on the three-quarter arc material bag belt 8; Step 6: After cutting, the cutter 401 continues to extend to push all the material bags into the respective falling channels of the falling material covers 5, and the material bags fall to the bottom of the falling channels; the third motor 404 drives the rotating disk 403 to reverse a certain angle, so that all the cutters 401 retract and return to their original positions; Step 7: The fourth motor 605 drives the wheel 604 to rotate one circle, and the protrusions 607 lift the swing rods 603 one by one in turn, so that the unloading doors 601 are opened one by one, and the material bags are put into the packaging conveyor line from the lower part of the cylinder 1 one by one; and steps 1 to 5 are performed at the same time; Step 8: Repeat steps 6 and 7.
